Cabling ERX Routers
NOTE: You can use a wire-wrap gun to attach wires to pins.
2. Attach the opposite end of the external timing cable or wires to your network’s
clock source A.
3. Repeat Steps 1 and 2 for the Clock B connections.
Management Ports
NOTE: This section applies to all ERX routers.
The Console section of the SRP I/O module has two ports for management
access. (See Figure 24 and Figure 25.)
The 10/100Base-T Ethernet port accepts an RJ-45 (male) connector, providing
an out-of-band connection for LAN access through a Telnet session or SNMP.
The RS-232 port accepts a DB-9 (female) connector for direct CLI access
from a console terminal.
The console port is considered a data terminal equipment interface (DTE).
Direct connection to a terminal or PC (which also have DTE interfaces) requires
a crossover cable.
